Key Finding: The brain activates nearly identical neural networks during mental rehearsal (motor imagery) as during actual physical performance. Repeated visualization creates neuroplastic changes equivalent to physical practice.
Key Finding: Handwriting activates broader, more elaborate brain connectivity patterns than typing, creating stronger memory encoding and supporting neuroplasticity. The oscillation between divergent thinking (generating possibilities) and convergent thinking (selecting specific outcomes) predicts creative ability and facilitates neurological change.
